4 Claims.

My invention relates to a combined road map and card holder, and it consists in the constructions, arrangements and combinations herein described and claimed.

It is an object of the invention to provide a map holder wherein the map will be supported in a manner permitting movement of the map in the direction being travelled so that the route may be readily followed.

It is a further object of the invention to provide a novel construction of take-up means for the map.

It is a still further object of the invention to provide novel means for attachment of a map holding device.

A still further object of the invention is the provision of a map or card holding device which is cheap of. construction, readily installed and manipulated.

Additional objects, advantages and features of invention will be apparent from the following description considered in conjunction with the accompanying drawings, wherein Figure 1 is a top plan view of my holder applied to a steering column of a motor vehicle.

Figure 2 is a cross section on the line 22 of Figure 1.

Figure 3 is a perspective view of my holder having a map associated therewith.

Figure 4 is a modified form of support for the map holder.

Figure 5 is a plan view illustrating a mode of supporting a card or the like.

Figure 6 is a side elevation of a modified form of the device embodying a suction cup.

Figure 7 is a top plan view thereof.

Figure 8 is a sectional view of the support cap.

Figure 9 is a side elevation thereof.

The present invention is directed particularly to the display of a map to be followed by a motorist, and in carrying out the invention provision is made of a body plate Ill preferably of rectangular formation, upon the ends of which an ear H is formed. The ears II are formed as integral parts of the plate Ill and shaped to provide a bearing for respective map supporting members l2. The supporting members l2 are identical in construction, and are formed from a single strand of wire, as will now be described. The wire is bent intermediate its length to form a U-shaped portion l3, the bight portion of which is pivotally mounted in an ear II, as may be clearly seen in Figure 2. Respective end portions of the wire are then bent in clockwise and counter-clockwise directions, respectively, to define the circular clip members I2a, the terminations of the wires stopping short and lying slightly above the bend M of the clips, thus forming an entrance opening l5 to each clip I2a. With the supporting members l2 secured to the plate, it will be apparent that the clips l2a positioned at respective ends of the plate lll will be aligned, and the axis of the clips lie in a plane parallel with but outwardly of the longitudinal edges of the plate.

The plate ID has an aperture formed medially thereof receiving a screw I 6, and upon the underside of the plate, a clamp plate I1 is positioned apertured to receive the screw I6, and between the main plate [0 and the clamp plate H, a sup port member I8 is secured, by tightening of the nut l9 upon the screw IS. The plate ill at points surrounding the opening for the screw "5 may be slightly dished as at 28), to provide a resilient clamping action of the support member l8, and 0 obviously, this area may be corrugated for lending greater stability to the plate. It will be obvious that the holder may be rotated about the bolt 16 for placement of the map, and it will also be apparent that the holder may be adjusted longitudinally of the support member IS.

The member H3, in the present instance, is formed from a suitable gauge wire bent intermediate its length to provide two parallel leg portions 2|, the terminations of which are bent downwardly at right angles (see Fig. 3) to form anchorage studs 22.

A mounting ring 23 is provided of a size to fit the steering post 24 of a motor vehicle, and in the present instance, consists of a split ring, the ends of which are bent to define opposed ears, the latter being apertured to receive a clamp screw 25, by means of which, the ring may be secured to the post. At points spaced so as to receive the studs 22 of the support member, a pair of outwardly bent semi-circular sockets 26 are formed in the ring, the radius of these sockets being slightly less than the diameter of the studs 22, and it will thus be apparent that with the studs 22 disposed within the sockets, tightening of the screw 25 will draw the studs into snug contacting relation with the post 24, thus holding the assembly secure.

In use, the map to be displayed is rolled at each end toward the center (see Fig. 3) the end 2'! being wound in a clockwise direction while the end 28 is rolled in a counter-clockwise direction. The clips l2 being swung to a vertical position upon the plate HI, so as to align the clips I2a at respective ends, the rolled ends 21-28 are slid endwise through the clips l2a at respective sides of the holder, the map portion 29, which is to be displayed having been admitted through the entrance opening !5 of the clips, being supported at the bent portions M of respective clips. The map will thus be supported revolubly within the clips 92a and when it is desired to move the map to bring into view a further route on the map, the index finger of the motorist is inserted into one of the rolled ends to engage the end of the map and by turning the finger, the map will be caused to be further rolled, which will obviously cause unrolling of the other rolled end, thus displaying a further portion of the map.

In Figure 4, I have illustrated support of the map holder, by means of a suction cupliii, permitting the holder to be afiixed to a smooth surface such as the instrument board or the windshield of the vehicle, or any other fiat surface.

In Figure 5, the holder is shown as a support for a registration or similar card, and in this use, the clip members l2 are swung so as to position the U-shaped portions l3 parallel to and above the plate H3. The card M is then inserted through the entrance openings I5 of the clips until properly centered, thereby retaining the card, by virtue of the overlying end portions 32 of the clips. It is not necessary that all the clips be employed in retention of the card, as any two will be ample and various positioning of the cards within the clips may be followed.

In Figures 6 to 9, I have illustrated a modified form of support, embodying the suction cup, and in this instance, the support [8 is identical to that previously described and comprises the legs 2|, studs 22 secured to the steering post 24' by the mounting ring 23'.

A mounting cap 33 is provided slidably mounted upon the legs 2i and as shown in Figure 8, has a circumscribing annular flange 34 slotted at diametrically opposite sides as at 35 and through which the legs 2 l extend. The length of the slots 35 are slightly less than the normal bowed relation of the legs 2i so that when the legs are positioned through the slots, it will be necessary to compress the legs slightly to admit them through the slots. Release of the legs will permit the legs to assume their normal bowed relation, firmly gripping the cap at the ends of the slots.

The cap 33 includes a convex top 36 of a diam eter to receive a suction cup 30', the latter having fixed thereto the body plate Ill and clip members l2a, as previously desired. Obviously, with the sliding plate mounted upon the bracket and secured to the column 24', the map or card holder may be secured to the plate 36 by the suction cup, or it may be detached from the plate and the suction cup and its holder then attached to any flat, smooth surface.

It should be noted that in all forms of the device, the map or card holder is slidable adjustable upon the legs 2 l2 I, permitting movement of the holder to a position inwardly or outwardly of the steering post.

While I have shown and described preferred forms of the device, this is by Way of illustration only, and I consider as my own, all such modifications in structure as fairly fall within the scope of the appended claims.
